Typhleotris
''Typhleotris'' is a genus of cavefish that are endemic to caves in southwestern Madagascar. Although traditionally considered to belong to the family Eleotridae, studies show that they represent a distinct and far-separated lineage together with the '' Milyeringa'' cavefish from Australia, leading some to move them to their own family, Milyeringidae.

Typhleotris Mararybe
''Typhleotris mararybe'' is a critically endangered species of fish in the family Milyeringidae, the blind cave gobies. It is a troglobitic species endemic to cave habitat in southwestern Madagascar. It is unique among known cave-dwelling fish in that is both blind and darkly pigmented.Sparks, J. S. and P. Chakrabarty.

It has well-developed nonvisual sensory systems and dives to avoid approaching objects. The fish was first collected in 2008 and was described to science as a new species in 2012. Description ''Typhleotris mararybe'' is about long. The body is uniformly dark brown in color, and the fins are mostly white with brown bases.

Typhleotris Madagascariensis
''Typhleotris madagascariensis'' is a species of fish in the family Milyeringidae that is endemic to Madagascar, where it is only known from underground waters in the southwestern portion of the island. This cavefish is blind and lacks pigmentation, and can reach a standard length of . This species is known from more than 10 caves and sinkholes in the Mahafaly Plateau region, in places where the water temperature typically ranges from and the pH is slightly above neutral. Although considered endangered because of its restricted range and not found to be common anywhere in its range in earlier studies, recent surveys found that the species is locally abundant, occurring in especially high numbers in the Andranoilove, Andriamaniloke, Lalia and Mitoho caves. In the southern part of its range, ''T. madagascariensis'' co-occurs with '' T. mararybe'', which is not as common or widespread. ''T. madagascariensis'' feeds on various invertebrates.

Cavefish
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, Troglomorphism, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.Romero, Aldemaro, editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. Helfman, G.S. (2007). ''Fish Conservation: A Guide to Understanding and Restoring Global Aquatic Biodiversity and Fishery Resources'', pp. 41–42. Island Press. There are more than 200 Species description, scientifically described species of obligate cavefish found on all continents, except Antarctica. Although widespread as a group, many species have very small ranges and are Threatened species, threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Typhleotris Pauliani
''Typhleotris pauliani'' is a critically endangered species of fish in the family Milyeringidae that is endemic to Madagascar, where it is only known from a few caves and sinkholes in the southwestern portion of the island. This blind cavefish lacks pigmentation and can reach a standard length of . It feeds on invertebrates and guano. Part of its range receive some protection, but the species is threatened by disturbance from recreational activities (from tourists and locals) and collectors of guano. The specific name honours the French entomologist and former deputy director of the Institut de recherche pour le développement in Madagascar, Renaud Paulian (1913-2003), who collected the type specimens as well as contributing a lot to the knowledge of the biogeography Biogeography is the study of the species distribution, distribution of species and ecosystems in geography, geographic space and through evolutionary history of life, geological time.

Milyeringidae
Milyeringinae, the blind cave gobies, is a subfamily of gobies in the family Eleotridae. There are two genera and six species within the subfamily: one genus ('' Milyeringa'') is restricted to caves in the North West Cape region of Australia and the other (''Typhleotris'') to underground water systems in Madagascar. They are all troglobitic species and have lost their eyes. Genera The two genera in the family are: * '' Milyeringa'' Whitley, 1945 * ''Typhleotris'' Petit Petit is a French-language surname literally meaning "small" or "little".

Milyeringa
''Milyeringa'' is a genus of blind cavefish from the Cape Range and Barrow Island, northwestern Australia. Although traditionally considered to belong to the family Eleotridae, studies show that they represent a distinct and far-separated lineage together with the ''Typhleotris'' cavefish from Madagascar, leading some to move them to their own family, Milyeringidae. The generic name is taken from Milyering which is southwest of Vlamingh Head in the North West Cape of Western Australia, the type locality for ''Milyeringa veritas''. Species The recognized species of this genus are: * '' Milyeringa brooksi'' Chakrabarty, 2010 * '' Milyeringa justitia'' Larson & Foster Foster may refer to: People * Foster (surname) * Foster Brooks (1912–2001), American actor * Foster Moreau (born 1997), American football player * Foster Sarell (born 1998), American football player * John Foster Dulles (1888–1959), America ..., 2013 (Barrow cave gudgeon) * '' Milyeringa veritas'' Whi ...

Glossogobius Ankaranensis
''Glossogobius ankaranensis'' is a species of fish in the family Gobiidae. This cavefish is endemic to the Ankarana Reserve in Madagascar. Its natural habitat is inland karsts. Cave system The Ankarana Mountain Range, formed by middle Jurassic sedimentary rock, is located in northern Madagascar, and its highest mountain is about above sea level. Several trees grow in the mountains' canyons and downfallen caves. Evergreen trees especially have an advantage due to the waters from a system of rivers that flows through the caves. Two important rivers enter the mountain range, the Andranotsisiloha and the Besaboba. These rivers are perennial and provide essential nutrients and habitat for an immense amount of organisms such as ''G. ankaranensis''. This species was found in the Second River Cave. The only approachable section of the Second Cave River is long and the deepest point is with a width of . The water temperature benefits all organisms it houses because it oscillates ...

Georges Petit (ichthyologist)
Georges Petit (; 11 March 1856 – 12 May 1920) was a French art dealer, a key figure in the Paris art world and an important promoter and cultivator of Impressionist artists. Early career Petit was the son of François Petit, who founded the firm of art dealers at 7, rue Saint-Georges (Paris) in 1846. Within just a few years, the ''Galerie François Petit'' was among the most powerful firms in the French art market. According to Robert Jensen in his book ''Marketing Modernism in Fin-de-Siecle Europe'', the auction house assumed, "multiple roles that ran the gamut from certifying the authenticity of the object, to guiding it through the hazards of the marketplace, to establishing its provenance and enlisting critics and historians to situate the artist's importance." Georges Petit inherited the firm, as well as a château and 3 million francs in 1877. He constructed a town house on the rue de Sèze. His annual expenses amounted to some 400,000 francs. That's what he spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...
